"Pnocron and Jenn BARRETT 'PRENDERGAST,

bothresiding at thecity "of Ottawa, Prov-' ince of-Ontario, Dominion of Canada, having invented certain new-and useful Improvements in Film-Winding Devices, do hereby declare the following to be a full, clear, and

- exact description of the same, such as will en-- 0 able others skilled in the art to which Itappertains .to make and use the-same.

The invention relates to film w1nd1ng'de,

vices, for use with moving picture films, and

the objects of the invention are to. provide an apparatus whichwill wind the film after ithas passed through the lantern on to a spool in such a manner that there is no necessity Qto re-windthe filmbefore it is ready for use asecond time, thus not only saving the time and labor occupied in re winding, but reducing the wear and tear of the film very,

materially.

The "nvention consists essentially in the novel construction and arrangement of parts more particularly set forth in the accofnpanying specification and the drawings that form part of the same.

In the drawings: Figure-1 is a perspective view of a portion of the apparatus with. .the sliding arm in its j out position. Fig.-

2 shows .an elevation partly in section of. the device with the sliding arma in its in position. Fig. 3 shows a perspective'view of a suitable spool for use with the device. Fig.

4 shows a perspective view of a suitable formof adjusting gear adapted to operate the adjusting rollers which guide the film when it is being wound spirally inward on its spool. Fig. 5 shows a diagram, indicating the method in which the device operates, and the path taken by the film during re-winding.

Referring to the drawings: 1 is the-frame which may be of cast iron and has provision such as the bolt-holes 2 or securing to their floor or .i-e-winding bench and also has a vertical arm. 3 provided atzits upper extrenr" ity with a horizontal orifice--4'and means 5 for securing a horizontal spindle Gin theori-a.

fice. a

7 is-a pulley rotatably mounted on the.

spindle 6, andhaving provision, WhlCll maytake the form of a pin- 8adapted to fit the groove 9, or other suitable means of 'revent- 1 ing lateral movement of the pulley on the i spindle" 6.

Patented 0a. 13, 1914.

10 is the winding-drum, consisting of a disk or armsll with a cylindrical flange 12-;

= and in the flange 12 commencing fromthe extreme outer edge 13; is a-single narrow slit 14 parallel to the axis of the winding drum, 30

and out nearly the whole way across the flange 12. This slit is adapted to allow the end '15 of the film being re-wound to pass through it, but narrow enough not to allow the clip 16 which isthen fastened to the end 5 15 of the film, to pass it; thus the end of the film issecured' at the outside of the drum, preparatory to re-winding which commenceswith the first coil being woundin the inner periphery of the winding drum 11, and the subsequent coils on the inside of the first coil; thus the film is re wound spirally inward, commencing fromthe outside.

17- is ap late provided with a plurality. of

lu 1- a flange 18 on its outer periphery, and is centrally and non-rotatably secured to the spindle 6; preferably in a manner that, it may be removed when F desired, as v for instance by the removal of the screws 19.

20 is a distance piece, which is preferably 86 :1 secured to the plate 17, and is provided with orifices or bearings 21 suitable for receiving the ends 22 of the roller adjusted screws 23, whose opposite ends 24 are. journaled in the lugs or flange 18,. in such a position; as to make the adjustment screws 23 pointiradially outward from the center of the device;

also allowing them free rotation but no end 25 are nuts adapted to be operatedbythe 9Q screws 23 radially inward or outward,'"a'nd each having a pin 26 extending at right angles to the adjusting'scre'ws, on which pin I is secured the'roller. 27, The nuts 25 may either be made solid where they engage with the-screws 23 or may be made split and provided with a hinge 28 and locking device 29 as shown in Fig. 4.

' 30' is fa; star-wheel attached to, or

iormeias part of the screws 23; at the'end' 22 thereof, and adapted to be actuated by the interprojection 31 which is formed on the winding drum diskor arms 11 this pin causes the star-wheel to rotate a traction of a revolution for each complete revolution of the winding drum; the amouiit of the fraction of a revolution being] governed by the number of teeth in the said star-wheel." I 32 is the film spool composed 6f the two side plates 33 andaeeach of which is preferably a sheet metal lamination comprising I an outer ring 35, as manyarms 36 as there are adjustment screws 23 used in the "particularidevice for which it is adapted to be .used, each of such arms 36 having a radial slot 37 adapted to provide a clearance for thefroller 2.7 and if found desirable, the

edge 38 of the said slot 37 may be bent out- 1 ward, in order to strengthen the side plates;

also the inner 39 and outer circumference 40- may be flanged for the same purpose.

The side plates are held together by a drum 41arrahged withfits axis concentric with the axis of the device and having a slot cut away coinpletely to allow the film entry to the spool from the inside thereof at each side of the slot arethe rollers mounted on pins 42. v

The side plate 34 ispi ovided with any suitable means of attachment, such. as the split expanding pins 43, tothe plate 17; so

that the spool-is to all intents and purposes when mounted on the device, a non-rotatable fixture, in between the'walls or side" plates of which the fihn is to be reswound;

44 is a spindle securedat'one of its ends into the'lateral projection 45 of the frame 1,

' and provided at its opposite end with a head or collar 46, or other suitable means for pre venting the removal of the sliding arm 47. Y J A 'keyway4'8 is cut in this spindle 44,

adapted to receive the key 49 secured to the sliding arm 47, and this keyway may extend from the head 46 of the spindle to where the spindle is secured to the lateral arm 45.

' .50 is a spring fitted to a recess atthebottom of keyway 48, and is secured thereto at one of its ends by the, screw'or rivet 51,

J while the other end 52 is adapted when in its 1 assumes the position indicated by dotted normal position. to rest against the end of the key 49, atsuch time as the sliding arm 47 is adjacent to the arm 45 of the frame; thus locking the sliding arm in this position.

By depressing. theiend 52 of the spring into the recess in the spindle formed to receive it, the arm 47 may be pulled out till it lines in-the drawing, or until it is touching I the head 46*of the spindle; and'tl'lis distance is sufiicient toallow ofthe film spool 32 being withdrawnin a lateral direction from the windingdrum 11, and then lifted out.

without touching either the winding drum .;or the spindle 53 which is attached-to the '55 i I sliding arm 47.

' The spindle 53 may be welded into the sliding arm, or may be adjustabl secured therein as shown the drawing, a d isipr ovided at its end remote from-the arm with a projection 54 adapted to center the spindle,

\ and tokeep it central, with the rest of the device, when the said projection enters it-' self in the centenof the plate 17.

' 55 a loose pulley rotatablysecured to thesaid spindle 53, and provided with means such as the pin'56 acting in the groove 57 formed in the spindle, ad end playof the pulley on the spindle. This pulley may be formed of wood if found suitable, and is preferably provided on its periphery with a slightly raised thread 58,

of the film which is to be re-wound in the it may assist in introducing the end of the film into the device at the commencement of the reg-winding. 59 is a jockey, pulley set at such an angle pare the film for the helical single twist it tatably mounted on aspindle 60', and also has on its side remote from the axis of the which is designed to prevent excessive twisting' or buckling of the film, also is adapted to prevent the film coming off the pulley.

the end of the film is introduced into the device by passing it between the rollers 59 and 61 and then giving it approximately one give one the correct pitch or amount of before the lens onto a spool, so arranged that the film is wound outward'on itself and therefore before using the film again, it has to be re-wound on to another spool, and this ably simpler. The spools when full on any suitable form of faceplate or spindle ,passed through the lantern out. to an exactly they ,are'immediately ready for'use again withoutfurther work or delay. p

What we claim as our invention is a combination, a'frame; aspindle; a pulley; a peripheralldy flanged drum secured to said u ley and a apted to rotate on said spindle slit being adapted to receive and have secured thereto the end of a film;- guide pulleys adapted to guide the film into a spool carried'by the aforesaid spindle, and guide of a pitch a trifle greater than the width device.
